Method:
After soaking the dal and rice, rinse and grind along with red chilli, salt and hing with some water to a coarse paste. The batter should be of dosa batter consistency-neither too thick nor too thin.
Add rest of the ingredients and mix well.
Heat a flat griddle. Spread some oil. When the griddle is hot, pour a ladle full of batter and spread it in circular fashion. Drizzle oil around the corners. When one side turns golden brown, flip and cook the other side.
